Clin Exp Pediatr. 2022;65(7):350-357.   Published online December 9, 2021
Question: What is prevalence of bacterial pathogens causing sepsis and their antimicrobial susceptibility over 20 years?
Finding: Coagulase-negative remains most common causative organism. The most common gram-negative organism was Klebsiella pneumonia. The susceptibility of staphylococcus aureus and K. pneumonia showed increased susceptability to oxacillin, cefotaxime and amikacin, gentamicin, respectively.
Meaning: Answers to the question asked is important in choosing antimicrobials and to monitor emergence of multidrug-resistant organisms.

Clin Exp Pediatr. 2014;57(12):538-541.   Published online December 31, 2014

Varicella is usually considered to be a benign disease in healthy children; however, serious complications can occur such as necrotizing fasciitis and toxic shock syndrome. We describe a 38-month-old girl with necrotizing fasciitis and streptococcal toxic shock syndrome following varicella. She was previously healthy and vaccinated against varicella at 12 months of age. She had been diagnosed with varicella three...

Hypokalemic periodic paralysis; two different genes responsible for similar clinical manifestations
Hunmin Kim, Hee Hwang, Hae Il Cheong, Hye Won Park
Clin Exp Pediatr. 2011;54(11):473-476.   Published online November 30, 2011

Primary hypokalemic periodic paralysis (HOKPP) is an autosomal dominant disorder manifesting as recurrent periodic flaccid paralysis and concomitant hypokalemia. HOKPP is divided into type 1 and type 2 based on the causative gene. Although 2 different ion channels have been identified as the molecular genetic cause of HOKPP, the clinical manifestations between the 2 groups are similar. We report the...

The hemolytic uremic syndrome (HUS) is a rare disease of microangiopathic hemolytic anemia, low platelet count and renal impairment. HUS usually occurs in young children after hemorrhagic colitis by shigatoxin-producing enterohemorrhagic E. coli (D+HUS). HUS is the most common cause of acute renal failure in infants and young children, and is a substantial cause of acute mortality and morbidity; however,...

Clin Exp Pediatr. 2007;50(9):862-867.   Published online September 15, 2007
Purpose : The impulse oscillometry (IOS) is applicable to young children because it requires minimal cooperation and a non-invasive method to measure the mechanics of respiratory system. This study aimed to develop the reference values in school-aged children in Korea, using IOS which is a modification of forced oscillation technique (FOT). Methods : Measurements were performed in 92 previously untrained healthy...

MELAS(mitochondrial myopathy, encephalopathy, lactic acidosis, and sroke like episodes) is a major subgroup of heterogeneous mitochondrial encephalopathy. Recent advances in molecular genetics revealed specific mutations in the mitochondrial DNA causing MELAS. We described clinical and molecular genetic findings of a 13-year-old boy with MELAS syndrome associated IDDM(insulin dependent diabetes mellitus). For molecular genetic studies, DNAs from peripheral blood nucleated cells were used. And the A→G...
